🐞 [BUG]: Video playback includes audio in preview

[thinkjrs]

Describe the bug

During QA, music auto-played on repeat when uploading video files with sound.

Noteworthy, once two files were uploaded both files' sounds played simultaneously

To Reproduce
Steps to reproduce the behavior:

1. Upload a video with sound
2. With speakers on, here the sound

Expected behavior
No audio included in video upload previews. This gets confusing, as it implies audio will be playing for ads which is not the case for Tincre ad placements at the moment.

We need a simple controls attribute on the video DOM property within the AdDisplay component.

For example,

<video controls muted>
  <source src="my-video.mp4" />
</video>

See the Mozilla docs on the topic: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video.

Note: the controls parameter above is not necessary for muting, it is merely included as an example.
